My friend teaches religion at a local Catholic highschool. One day a few years ago, a couple of his students excitedly informed him that the Pope was coming. He went, “What??” And then he realized that they were Coptic Orthodox, and were talking about the Coptic Pope’s visit, not the Roman Pope.

Pope is really a term of affection, coming to the Greek "papas", which simply means "priest" but is related to "father". The Russian colloquial term for "priest" is "pop" but it is usually transliterated as "pope" as well, not to introduce the unwanted modern connotations.

The Coptic Church is not in communion with either the Orthodox nor the Catholic Churches, so they have their own system of clerical designations.
